Which value would be a solution for x in the inequality 47-4x<7

Mathematics
1 answer:
cluponka [151]3 years ago
5 0

Answer:

x > 10

Step-by-step explanation:

47-4x<7

Subtract 47 from each side

47-47-4x<7-47

-4x < -40

Divide by -4.  When dividing by a negative, flip the inequality.

-4x/-4 > -40/-4

x > 10

Answer:

(\frac{5}{2},-\frac{7}{2})  

Step-by-step explanation:

<u><em>The complete question is</em></u>

What is the midpoint of the segment shown below?

(1,-1) (4, -6)

we know that

The formula to calculate the midpoint between two points is equal to

M(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

we have

(x_1,y_1)=(1,-1)\\(x_2,y_2)=(4,-6)

substitute the given values

M(\frac{1+4}{2},\frac{-1-6}{2})

M(\frac{5}{2},-\frac{7}{2})

how do the graphs of f(x) = sin x and g(x) = sin2x+3 compare. Must make two selections of the following that apply.
Elena L [17]

Answer:

The correct options are:

  • g(x) is shifted three units higher than f(x).
  • g(x) has a period that is half the period of  f(x).

Step-by-step explanation:

We have to compare the graphs of the function:

f(x)=\sin x

and g(x)=\sin 2x+3

We have to select the correct options among the following:

As we know that the period of sine function is 2π.

i.e. Period of function f(x) is: 2π.

The period of sin(2 x) is π.

Hence, the period of the function g(x) function is π.

  • Hence, the period of g(x) is half the period of f(x).
  • Also we could observe that g(x) is shifted 3 units upward.

Answer:  Graph D (bottom right corner)

======================================================

Explanation:

The equation y = 3x+3 is in slope intercept form y = mx+b

m = 3 = slope

b = 3 = y intercept

In this case, both the slope and y intercept are the same (though in general they tend not to be).

The positive slope value means the line goes uphill as you move from left to right. The positive y intercept means the diagonal line crosses the y axis somewhere above the horizontal x axis. Specifically, it crosses the y axis at y = 3

Graph D is the only graph that has such a line on it. Graphs A, B and C have the positive slope line where they have a negative y intercept, so we can rule them out.

You can use graphing tools such as Desmos or Geogebra to help confirm this answer. You could also make a table of values, and plot each point, to form the lines. Two points is the minimum amount needed to form any line.
